They have let a media studies student do the diagrams so they are '3D and live graphics' very fancy looking but try to put the diagrams into lecture notes.

Can a Climate Fairy named Kerry read a chart?  If he could, he would note that we seem to be getting further away from that magic +1.5 C.  And we didn't have to do anything.  Time to turn the boat around and head back to the Kerry Mansion in Boston and work on his yoga.

It is very hard to find graphs of water vapor in the troposphere. Here is the link to data............care to investigate?

I quickly reproduced the "annual uncompensated (residual) CO2" values (October to October CO2 change) that Spencer used and compared them to the UAH Lower Troposphere temperature anomalies for the tropical and northern hemisphere.  As he showed, there is a very close relationship to EL Nino events throughout the series.  The front edge of each CO2 block is November, so I need to check where in the 12-month block (if any) where CO2 spikes.  There is also something wierd in the 1988-94 time period.

This also not the first time this has been done.  The second chart is better than mine.  I found it in my saved images, but must track down the source.

"The Time Has Come to Rein In the Global Scourge of Palm Oil

The cultivation of palm oil, found in roughly half of U.S. grocery products, has devastated tropical ecosystems, released vast amounts of C02 into the atmosphere, and impoverished rural communities. But efforts are underway that could curb the abuses of this powerful industry.

These days, palm oil accounts for one-third of total global vegetable oil consumption."

"Insensitivity of global warming potentials to carbon dioxide emission scenarios

Ken Caldeira & James F. Kasting

Nature volume 366, pages 251–253 (1993)Cite this article



Abstract

GLOBAL warming potentials for radiatively active trace gases (such as methane and chlorofluorocarbons) have generally been expressed1–2 relative to the time-integrated climate forcing per unit emission of carbon dioxide. Previous attempts to estimate the integrated climate forcing per unit CO2 emitted have focused on perturbations to steady-state conditions in carbon-cycle models. But for non-steady-state conditions, the integrated climate forcing from a CO2 perturbation depends both on the initial conditions and on future atmospheric CO2 concentrations. As atmospheric CO2concentrations increase, the radiative forcing per unit CO2 emitted will become smaller because the strongest absorption bands will already be saturated. At the same time, higher concentrations of dissolved carbon in the surface ocean will reduce the ocean's ability to absorb excess CO2from the atmosphere. Each of these effects taken alone would affect the climate forcing from a pulse of emitted CO2 by a factor of three or more; but here we show that, taken together, they compensate for each other. The net result is that the global warming potential of CO2 relative to other radiatively active trace gases is nearly independent of the CO2emission scenario. Thus, the concept of the global warming potential remains useful, despite the nonlinearities in the climate system and uncertainties in future emissions."

Here is an old article from the Chiefio on CO2 sources, sinks and mechanics of entering and leaving the atmosphere.  Some good maps too.  For reference please note that 2000 (the map) was a La Nina year (see chart a couple of posts up) and CO2 flux was amazingly high and extensive into the Central Pacific Ocean.  Do CO2-rich upwelling waters need a small boost in tropical heating to more efficiently translocate to the atmosphere?  Or do they just bubble out like a can of soda?

While this must be discouraging to the true believers, at least it seems that maybe there is some pragmatism in European leadership, in the sense that they seem not to have torn down all the coal plants.

Speaking as someone with a cup of fore-brain removed - and what was left now being sprayed with radiation and given chemo'therapy' to prevent any healing I can only say that I followed what it was saying. Perhaps you should reduce your 'Fosters' intake?

Total Atmospheric CO2 and Anthropogenic CO2 Emissions (1958-2021) With Comparisons to ENSO and UAH Temperatures

I found an official data source provides annual World (and country) CO2 emissions.  I converted the World data from gigatons to PPM based on a conversion factor I found and integrated this with the Mauna Loa CO2 data.  All data were converted back to monthly values. 

Chart 1 shows the residual (October to October) CO2 values compared to monthly anthropogenic data.  Total CO2 change is up to 7 times greater than Anthropogenic and has a greater positive slope over the 63 year period.  It is apparent that CO2 spikes occur largely during La Nina events.  But these are superimposed on an upward trend, which suggests that warming oceans give off more CO2.

Chart 2 is a replica of the one I've used to show the lagging relationship of UAH Lower Troposphere temperatures to ENSO.  It seems equally clear that CO2 spikes lag UAH temperatures, which lag EL Nino events.

That’s a great article and exposes Gore and Nye for the frauds they are.

Fortunately, my proposed experiment for testing Nautonnier’s hunch that LWIR will cool the ocean doesn’t have the fatal flaw in the Gore/Nye experiment. The LWIR passes directly to the water surface through air. Putting glass in the way would absorb the LWIR.

One thing I would caution here for some who may not read the whole article. This article does not conclude that CO2 is not a “greenhouse gas”.

Watt’s words are “I should make it clear that I’m not doubting that CO2 has a positive radiative heating effect in our atmosphere, due to LWIR re-radiation, that is well established by science.”
